F22a6 manual transmission LSD conversion?

[Jak3l]

Hey guys, I've had this on my mind for awhile now and I haven't found much info about it so I figured I'd just ask. I have a f22a6 with the stock manual transmission and I've been wondering if there is a way to convert it to LSD. I know they have the LSD prelude trannys but Im interested to see if anyone has done this with the stock f22 transmission. I'm gonna be boosting my car soon and I'd like to keep the longer gears and add LSD if possible. Anyways thanks in advance for any help it is much appreciated!

Yes you can.

Options

Weld - I've never tried it
Phantom Grip - Don't know anyone whos tried it. But I do plan to give it shot in my Lemons car very soon.
Aftermarket LSD - Best choice

FYI - Honda LSD will not fit non LSD trannys

Even though these videos are for a B-series tranny, The process is the same

I had a Quaife LSD in a F22 transmission 10 years ago. Worked great.

i have a Mfactory in my new build, cant say how good it is(as im still in process of finishing it), but it has all good reviews everywhere. but it is another option

I also have the mfactory lsd. I didn't get to beat on it too much but i like it's performance. The price was also a factor. Also the current 2nd generation is suppose to be lighter.

Quaife is always a good choice. It worked really well in my brothers 350whp Rado.

Don't weld it. Slag chips off and ruins gears. Just don't buy OBX and you should be fine. Quaife seems to be the way to go if you can't find a factory transmission.

I have a Quaiffe in my trans and I love it. They are a bit pricey, but they are worth it! Lifetime warranty is a plus.

I can't speak to the mFactory, but they have good reviews from others...

Ya, i never heard anything good about Phantom Grip LSDs. Mfactory or Quaife FTW.

[Rilas]

Which is odd about the Phantom Grip, I've read a ton of Legend owners have it and have been happy with them. But I think it is literally their only non OEM option.

[deevergote]

Phantom Grip isn't really an LSD. It's a step up from welding the diff, essentially. Fairly effective, and good if you're on a budget (and can find one for a decent price), but not likely comparable anything else. I've actually heard pretty good things about the Phantom Grip with upgraded springs.
Although I've owned a Phantom Grip for nearly a decade, I never actually got around to installing it.

MFactory and Quaife seem to be the favorites. If OBX still makes one, that's not a bad option either. OBX is really just a reverse-engineering firm (copycat company), but their LSD has had pretty consistent reviews. Especially once they made it to more exact tolerances (the earliest ones had to be rebuilt before they were good.)

Could you use the H trans for the LSD and swap the gears from the F trans? Or is this too big of a PITA compared to an aftermarket LSD in an F trans?

[deevergote]

If the H case can accept all the F gears, I don't see why not. That seems like a pretty backwards way to do it, though... unless an LSD H trans is readily available (and cheap.) A good aftermarket LSD unit will be superior to the factory LSD, too. And the factory LSD case won't be able to accept an aftermarket upgrade. The factory LSD is larger than the non-LSD.

What about the Wavetrac? I like their engineering a bit more than the Quaife but I don't know about any real world experience with any of them. I've been thinking of an Mfactory or Wavetrac for a bit of cheatyness in my race car

Oh and how is the install of an LSD? I've installed LSDs in rear diffs in RWD cars before but never in a FWD transaxle. Is it difficult to split the case and all that?

See videos I posted earlier, its the same process. You could look up my Swap Chronicles thread. I have videos there

[deevergote]

I haven't watched the videos, but I did discuss the process with a friend, and he mentioned that the annoying part can be shimming the unit to fit properly. I don't know if that applies to all mentioned, but he spoke of it as something that is often discovered as a surprise to people trying it their first time. I don't have any experience to offer legitimate help there, but it might be a good thing to look into before you're elbows deep in transmission bits.
